OK so had an appointment yesterday. 23 weeks and they measured my stomach and they said within two weeks I grew 3cms. so I asked the doctor what I weighed at 21 weeks and she said 25. So yesterday I measured 28cms. Getting worried a little. they scheduled me for an ultrasound on Friday so I am praying.
